摘要

The impact wrench (1) has hammer mechanism basket (4) in which hammer (2) is arranged. The hammer is actuated by a motor and carries flapping on a spindle (6). A trained section of a crank as curved path is arranged between the spindle and the hammer for carrying frictional movement of hammer on spindle. The arrangement of curved path is clock wise tuned on the rotation of the impact wrench.
